Hi Will and Dan,

	Thanks for your messages.  I did delete the core files previously; 
I have generated new ones by not restricting the machines I am using.  
They are in /afs/hep.wisc.edu/home/frankjp/core_files, along with a log 
file.  If either of you could help me figure out what is going on I would 
greatly appreciate the help.

	I find these, as I said, by noticing a process crash.  By
retricting the allowed machines in my submit file, I can get my processes
to finish, so I don't think it is my code (I've run thousands of jobs with
this code several months ago without noticing this issue).  I have no idea
how widespread it is, or whether it is something local to the machine I am
submitting from.

	Will, I can try set up my future runs in a local scratch directory
(is this what you recommend?) if you think that will help.  However, each
job writes minimal data (a few hundred bytes, I changed this in response
to similar comments from Steve a while back by removing intermediate
output).  Given this size, is the strain on AFS large?  Is some other
variable the appropriate one to consider, and not output size?  If so I
will certainly change my configuration, but I thought I avoided this.

Thanks for your help,
Frank
